He suffered grave wounds to the face and neck on Tuesday in a shooting in which another man was slain. Doctors on Thursday had declared Camacho brain dead before removing equipment that had kept him alive, Rio Piedras Hospital chief Ernesto Torres said.

Camacho was riding with a friend in San Juan when their car came under fire. The driver died at the scene.

There was no clear motive in the attack, police said, though Camacho’s slain friend was found in possession of cocaine.

Camacho struggled with drugs and alcohol throughout his career.

Former featherweight champion Juan Laporte, a friend since childhood, described Camacho as “like a little brother who was always getting into trouble,” but otherwise combined a friendly nature with a powerful jab.

“He’s a good human being, a good hearted person,” Laporte said as he waited with other friends and members of the boxer’s family outside the hospital in San Juan after the shooting. “A lot of people think of him as a cocky person but that was his motto … Inside he was just a kid looking for something.”

The retired boxer’s family was planning a wake in Puerto Rico and a funeral in New York, the daily El Nuevo Dia reported.

In the 1980s, Camacho was the WBC world champion at super featherweight and lightweight and held the WBO belt at junior welterweight.

He compiled a professional record of 79-6-3 in a career that ended in 2010, with notable victories over Rafael Limon, Freddie Roach, Ray Mancini and Roberto Duran twice. In 1997, Camacho knocked out Sugar Ray Leonard.
